In this scientific statements worksheet, students are given 35 statements and they are to identify if each statement is a fact, law, hypothesis, theory or belief.

Students identify map projections and examine polar maps. In this map skills lesson, students use a flat world map to identify various projections and calculate the distances between locations by using a map scale.

In this cardinal directions worksheet, learners read a 2-page review of cardinal directions and use a globe to respond to 5 questions.

Students explore the concept of latitude. In this geography instructional activity, students discover the global grid system and complete a map activity which require them to record the latitude of various cities in the world.

In this science worksheet, students look for the answers that are related to the concept of insolation and measuring different angles.

Students examine cloud types. In this cloud lesson, students identify cloud types, observe clouds and collect data, and analyze data to identify the most common cloud they observe overhead during the course of a month.

In this eclipses worksheet, students will compare diagrams of a total solar eclipse with a total lunar eclipse. Students will complete 6 short answer questions based on these diagrams.

Young scholars observe the movement of pendulums, they begin to understand the relationship between gravitational forces and the mass of objects, the changes in speed and direction of objects, and the distance between objects. They...

Students calculate the amount of solar radiation hitting the ground at their school compared to the solar constant. They also repeat the experiment at a water testing site and utilize a light probe to measure the light being reflected...

In this motion learning exercise, students calculate the initial angular acceleration, and the angular speed before and after impact for different objects. This learning exercise has 3 problems to solve.

Students describe stellar objects using terms such as stars, planets, satellites, orbits and light. In this sun and stars unit, students research stellar objects through seven individual lessons discovering star characteristics, how...

Sixth graders examine the purposes of maps.  In this Geography lesson plan, 6th graders practice using latitude and longitude on a map. 

In this planet science worksheet, students learn 6 facts about the planet Pluto. Students then read a short paragraph about the planet.
